I've noticed a few differences between the games on the two platforms as stated. For example, I can't seem to win cards in duel mode on my iPhone. Also, I can see the players who are currently in a particular room, something I'd like to do on the website version as well, although I know it could be done on the web in the past. Solo mode is also missing from the iPhone app. When I got temporarily blocked from the market on the web, I could still buy and sell cards via the app. Are these intentional, or is the app just outdated?
– App doesn't have forums
– App doesn't have public presets
– App doesn't have guilds
These three don't really matter to me, because I could use Safari for those. What matters is when you want to play the game on the phone, and I can't do it on the web so I have to use the app. And it's different there. But still, more functions would be better.
